How do PCR tests detect COVID-19?
Polymerase Chain Reaction (PCR) tests are a cornerstone of COVID-19 detection. Here's a brief overview of how they work:
Sample Collection: The process begins with collecting a sample, typically from a nasopharyngeal swab. This sample contains cells from the upper respiratory tract where the virus is most commonly found.
RNA Extraction: Once the sample is collected, the RNA from the virus (if present) is extracted. RNA is the genetic material of the virus and needs to be isolated from the rest of the sample.
Reverse Transcription: The extracted RNA is then converted into complementary DNA (cDNA) through a process called reverse transcription. This step is crucial because PCR works with DNA, not RNA.
Amplification: The cDNA is then amplified using a specific enzyme known as DNA polymerase. During this amplification, the target viral genetic material is copied many times to ensure that even tiny amounts can be detected.
Detection: The PCR machine monitors the amplification process. It uses fluorescent dyes or probes that bind to the viral DNA. If the virus's genetic material is present, the fluorescence increases, signaling a positive result.
Results: After amplification, the PCR machine generates data that indicate whether or not the virus's genetic material was detected in the sample. A positive result confirms the presence of COVID-19.
